What true colours, by the way? To be clear: Jones is someone who's relaxed about terrorists until they encroach on him to the point that the victims cease to be an undifferentiated mass who had it coming and turn into individuals about whom he cares. There is more joy in heaven, and all that, and perhaps this might him start to think that cheering on terrorists is wrong whoever their victims, because their victims are always innocent.
I think mass murder is wrong, full stop. Whoever the victims are: people in a club in Orlando, children in a school in Beslan, people drinking in pubs on the way home. I was, for what it's worth (in every sense of that gloomy phrase), at the solidarity protest about Orlando in my city last night.
Jones has spent a lot of time sucking up to horrible fascists, and has now learnt that when they say that they want to kill gay people, they aren't joking. That's great. Now could he stop cheering terrorists on whoever they want to kill?
